Hi John....it is connected to the casino on the ship. You get points on your card when you gamble. With the points you can get perks. I really don't gamble much. You had to earn 1000 points to get $10 cash back, but I never got close! The strawberries and $15.00 photo coupon were nice perks though.
I hope you enjoy Rosie's tour as much as we did. She will customize the trip also, if you have things you know you want to do.
